Costco's problematic opening week continued when an Eftpos outage left thousands queuing this morning.
The payment system failure led to many people having to abandon full trolleys of goods at the checkout while queues formed throughout the store.
Stuff NZ reported that staff members were seen making their way through the queues apologising to customers for the outage and were using mobile Eftpos devices to take payments at the tills.
It was reported that the machines were down for at least half an hour late on Monday morning.
